Form Field Hesitation & Abandonment Telemetry Snippet
Discover the exact form field that makes your visitors abandon. Drop in a 1KB, privacy-safe JavaScript telemetry snippet.
Problem it addresses
Develop a lightweight, privacy-safe form hesitation tracking library (form_telemetry.js): 1) Tracks time spent per field (focus to blur), correction count (backspaces), and last-interacted field upon abandonment, 2) Does not record keystroke text by design; field timing and correction-count events still require appropriate consent, minimization, and disclosure, 3) Pushes structured form_friction events to dataLayer, 4) Includes GTM container JSON and GA4 exploration guide.
Who it is for
PRO operating in high-growth e-commerce, digital publishing, and direct-response marketing across Saudi Arabia, UAE, and Egypt.

How to evaluate and use it
- Read the README first and confirm that the documented problem matches your use case.
- Inspect the listed files to find the data, tools, templates, and tests relevant to your task.
- Follow the repository’s Quick Start and check prerequisites before running commands.
- Compare outputs with documented examples and review limitations before using them in a decision or client workflow.
Quick Start from the README: python -m unittest discover -s tests · node --test tests/*.test.js · python src/aggregate_hesitation.py --help
Scope and limitations
- Performance Impact: Event listeners for focus, blur, and keystroke timing must use passive listeners and debounce routines to prevent input lag.
- PII Data Isolation: Field value contents are never logged or transmitted; telemetry captures field names, character counts, and hesitation milliseconds only.
- Bilingual Field Identification: Normalizes Arabic input labels (e.g. 'رقم الجوال') to standard telemetry keys (e.g. 'phone_input').
